Civilization goes back at least another 10,000 years, if we are willing to believe what our ancestors themselves claimed.

Analyzing the historical and archaeological evidence, Philip Coppens demonstrates that there is substantial proof that our ancestors were far more technologically advanced than currently accepted and that certain cultures interacted with nonhuman intelligences. Our ancestors were clearly not alone.

Built at the end of the last ice age around 9600 BCE, Göbekli Tepe in southeast Turkey was designed to align with the constellation of the celestial swan, Cygnus - a fact confirmed by the discovery at the site of a tiny bone plaque carved with the three key stars of Cygnus.
